Flow map route error

Resolver — Fri, 25 Apr 2025 08:15:45 GMT

Hello, I've created a flow map for displaying top n routes by order count. The problem is that not all routes are visible on map. For data I am using city, state, country and zip code, all locations were checked on map and there were no error with data itself, but whenever I put it as a full route in flow map, some and even top 2 lanes are not displayed.

1.Double-check your Top N calculation outside the map first.

Create a separate table visual showing exactly which Source-Destination pairs and counts are top.
Ensure that Flow Map is getting exactly those pairs.

2. Try to simplify the geography a bit.

Use City + Country or State + Country only.
Sometimes adding Zip Codes confuses the geocoding engine and causes routes to disappear.

3. Lower the Top N if possible.

Try Top 20 or Top 50 first.
Flow Map can choke if you push too many routes at once.

4. Check for duplicates or rounding issues.

If two routes have almost the same counts, and you have a Top N filter, sometimes minor rounding can push the expected routes out.

5. Try using Source Latitude/Longitude and Destination Latitude/Longitude directly.

If you can add lat/lon to your data, you bypass some of the geocoding guesswork.

6. Adjust settings inside the Flow Map visual

There is often an option like:
- "Route smoothing"
- "Avoid overlapping lines"
- "Force show all routes" (depends on the visual version)

7. (Last resort) Use an alternative visual

If Flow Map keeps failing, try the Route Map custom visual or even ArcGIS for Power BI.

They're heavier but more reliable for lots of paths.
